Abstract
Some tests of gravity theories—periastron shift, geodetic precession, change in mean motion and gravitational redshift—are applied in solar and stellar systems to constrain the cosmological constant. We thus consider a length scale range from to . Best bounds from the solar system come from perihelion advance and change in mean motion of Earth and Mars, . Such a limit falls very short to estimates from observational cosmology analyses but a future experiment performing radio ranging observations of outer planets could improve it by 4 orders of magnitude. Beyond the solar system, together with future measurements of periastron advance in wide binary pulsars, gravitational redshift of white dwarfs can provide bounds competitive with Mars data.
